Model
Lg WT7010C*
Rank #371 means 370 of the 388 washing machine models we track cost less to run each year; the 13th efficiency percentile means it uses less energy for its size than 13% of those models.
What does the Lg WT7010C* cost to run per year?
Almost nothing we track in this class costs more to run than the Lg WT7010C*: about $41 a year, rank #371 of 388. Normalized for capacity, it beats only 13% of washing machine models we track, one of the weaker efficiency results we track for the class. At a IMEF of 2.06, its integrated modified energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Midea MLTW62M7ACG at $40/yr runs a little cheaper and the Lg WT7060C* at $41/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A washing machine typically stays in service for somewhere around 10 years; over that span, the Lg WT7010C*'s $41/yr adds up to roughly $410 in electricity alone, before purchase price or repairs.
Also sold as: Lg WT7060C*, Lg WT7100C*.
By the numbers
The Lg WT7010C* normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $41/yr, here is what the Lg WT7010C* adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Lg WT7010C* costs about $410. That is roughly $210 more than the class median, which would run closer to $200 over the same ten years.
How the Lg WT7010C* compares
The washing machine class we track runs from $7 to $58 a year. At $41/yr, it runs about $21 a year above the class median of $20, and it is about $34 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 4.5 cu ft, the Lg WT7010C* is a mid-size washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone. The IMEF of 2.06 on this model, below the class median of 2.76, measures integrated modified energy factor; it is the number to compare directly against another model's IMEF if capacity is similar.
- Spin and wash efficiency (IMEF). A higher Integrated Modified Energy Factor means the machine wrings more useful washing (and a drier spin) out of every kilowatt-hour and gallon it uses.
- Drum volume. Drum volume sets the ceiling on how much a single cycle can wash, and it is usually the first driver of a washer's per-cycle energy use.
- Water heating. Cycle temperature, more than drum size, is usually what separates a cheap wash cycle from an expensive one on models with an internal water heater.
Common questions
Is the Lg WT7010C* cheap to run?
Not especially. At $41 a year it ranks #371 of 388 washing machine models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Lg WT7010C* cost per month?
Roughly $3.4/mo, spreading the $41/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 220 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $41 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg WT7010C* for its size?
13th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
